[0001] The present invention relates to a protective shroud for a dive watch.
[0002] Dive watches are generally equipped with a protective shroud made of transparent
elastic material that protects them from the inevitable impacts that they may undergo
during diving activity but that allows the visibility of the dial.
[0003] Such protective shrouds generally comprise a protective element for protecting the
dial and two projecting slots that allow the passage of a strap in a single piece
or the fixing of the two parts thereof.
[0004] Dive watches are often actual calculators and, in that case, on their dials, numerous
pieces of information appear that are necessary for managing the diver's activities
and for his/her safety.
[0005] It is therefore necessary for such information to be clearly visible on the watch
dial and, in a known way, greater visibility may be obtained with an increase in the
size of the dial and therefore of the dimensions of the watch, which implies the inevitable
drawbacks associated with such a trivial solution.
[0006] The technical task of the present invention is, therefore, to provide a system which
obviates the above-described technical drawbacks of the prior art.
[0007] Within the scope of this technical task, an object of the invention is to provide
a system that allows a clear view of the dial without an increase in the dimensions
of the watch.
[0008] The technical task, as well as these and other objects, according to the present
invention, are reached by providing a protective shroud for a dive watch characterised
in that it comprises a transparent lenticular element configured to enlarge the image
that appears on a dial of the watch.
[0009] According to another aspect of the invention, the lenticular element is convex.
[0010] According to another aspect of the invention, the lenticular element is configured
to cover and protect said dial of the watch.
[0011] According to another aspect of the invention, a rib is provided for distancing said
lenticular element from said dial of the watch.
[0012] Advantageously, the thickness of such rib, which distances the lenticular element
from the dial, and the lenticular shape itself of the lenticular element, allow the
enlargement of the figures that appear on the dial of the watch to be graduated.
[0013] Other characteristics of the present invention are further defined in the claims
hereinbelow.
[0014] Further characteristics and advantages of the invention will more fully emerge from
the description of a preferred but not exclusive embodiment of the protective shroud
for a dive watch according to the invention, illustrated by way of non-limiting example
in the accompanying figures of the drawings, in which:
figure 1 is a perspective view of a dive watch equipped with a protective shroud according
to the invention;
figure 2 is the perspective view of the protective shroud only; and
figure 3 is a section according to plane III-III of figure 1.
[0015] With reference to the figures mentioned, a dive watch is shown indicated overall
with the reference number 1.
[0016] The dive watch 1 comprises in a known way a case 10 that supports a dial 4 surmounted
by a protective crystal 11, and a strap 6 equipped with a buckle 12 for fastening
the watch 1 to the wrist of the diver.
[0017] A protective shroud 2 made of elastic material is fitted onto the watch 1.
[0018] The protective shroud 2, being made of elastic material, can be easily fitted and
removed from the watch 1 as needed.
[0019] The protective shroud 2 advantageously comprises a transparent lenticular element
3 configured to enlarge the image that appears on the dial 4 of the watch 1 and to
cover it and protect it.
[0020] The lenticular element 3 is convex and is arranged with its optical axis L positioned
orthogonally to the dial 4 of the watch 1.
[0021] As shown in particular, the lenticular element 3 is bi-convex, in the sense that
both faces 33, 34 of the lenticular element 3 are convex.
[0022] The lenticular element 3 is also flattened, having an extension in the direction
of its optical axis L that is substantially smaller than its dimensions in the orthogonal
plane to its optical axis L.
[0023] The lenticular element 3 has a substantially congruent shape to that of the dial
4, and thus will normally be circular if the dial 4 is circular, rectangular if the
dial 4 is rectangular and so on.
[0024] The protective shroud 2 further comprises a flange 7 that extends around the lenticular
element 3.
[0025] The flange 7 comprises two slots 5 for fixing the strap 6 of the watch 1.
[0026] The flange 7 has a first pair of angular sectors 36, 37 diametrically opposite the
lenticular element 3 configured for covering and protecting the edge of the case 10
of the watch 1.
[0027] The flange 7 also has a second pair of angular sectors 38, 39 diametrically opposite
the lenticular element 3 having the slots 5.
[0028] In the direction of the optical axis L of the lenticular element 3, the first pair
of angular sectors 36, 37 has a smaller extension than the second pair of angular
sectors 38, 39.
[0029] At the face 33 of the lenticular element 3 facing towards the dial 4 of the watch
1, a rib 32 is advantageously provided that supports the lenticular element 3 at an
appropriate distance from the dial 4 of the watch 1.
[0030] The rib 32 extends along the perimeter 31 of the face 33 of the lenticular element
3 facing towards the dial 4 of the watch 1 and therefore has a substantially congruent
shape to that of the perimeter of the dial 4.
[0031] The rib 32 will therefore normally be annular if the dial 4 is circular, shaped like
a closed broken line if the dial 4 is polygonal, and so on.
[0032] In particular, the rib 32 has a uniform thickness so as to be arranged uniformly
along the whole perimeter of the dial 4 of the watch 1.
[0033] The protective shroud 2 comprising the lenticular element 3, the flange 7 and the
rib 32 is made in various pieces as shown, or preferably in a single piece.
[0034] If it is in a single piece, in particular, it is made with a single transparent elastic
material having a selectively glossy surface finish at the flange 7 and the rib 32
so that only the part that defines the lenticular element 3 is transparent.
[0035] Clearly, as mentioned, the shroud can alternatively be provided in various pieces
joined together having the same or different elastic and transparency properties.
[0036] In conclusion, according to the present invention, better visibility of the dial
4 is obtained with a lenticular element 3 that acts as a magnifying glass.
[0037] The distance H between the internal face 33 of the lenticular element 3 and the surface
of the dial 4 can be varied so that, together with the choice of convexity of the
internal face 33 and the external face 34 of the lenticular element 3, it allows the
desired degree of enlargement to be provided.
[0038] The protective device for a dive watch as conceived herein is susceptible to many
modifications and variations, all falling within the scope of the inventive concept;
furthermore, all the details are replaceable by technically equivalent elements.
[0039] In practice the materials used, as well as the dimensions, can be any according to
the needs and the state of the art.
